Abstract :
Two sub-crosspoint physical topologies are proposed that places the decode circuitry beneath the metal-oxide RRAM crosspoint array. The first topology integrates only the row decode circuitry, while the second integrates both the row and column decoder. The topology for sub-crosspoint row decoding reduces area by up to 38.6% over the standard peripheral approach, with an improvement in area efficiency of 21.6% for small arrays. Sub-crosspoint row and column decoding reduces the RRAM crosspoint area by 27.1% and improves area efficiency to nearly 100%.
